A new luminescent platinum(II) chloride complex of 6-(5-trifluoromethyl-1,2,4-triazol-3-yl)-4,4′-dimethyl-2,2′-bipyridine

Synthesis of platinum complexes with 2-(5-perfluoroalkyl-1,2,4-oxadiazol-3yl)-pyridine and 2-(3-perfluoroalkyl-1-methyl-1,2,4-triazole-5yl)-pyridine ligands and their in vitro antitumor activity

“…On the contrary for 4b only one molecule of 1,2,4-triazole is coordinated to Pt(II) ion via N4 atom of triazole and N1 atom of pyridine, where the remaining two coordination sites of the platinum are engaged with two chlorine atoms. Similar complexes with 6-(5-trifluoromethyl-1,2,4-triazol-3yl)-4,4′-dimethyl-2,2′-bipyridine ligand have been reported [42]. In the complex 4a and 5a the coordination environment of Pt(II) ion is equal and the resonance signals of the pyridine protons are not shifted with respect to the ligand and they occur in the range 8.80-7.62 ppm.…”
